A Waupun firefighter made short work of a small fire that started in a wooden box used to set off fireworks.

The fireworks display began at 10 p.m. Friday during the Celebrate Waupun festival marking the city’s 175th anniversary.

Waupun Police Lt. Jeremy Rasch reported that around 10:30 p.m. — during the fireworks finale — one of the large wooden boxes used to light fireworks started on fire, but a firefighter used an extinguisher to quickly put out the flames.

While some residents reported that sparks were landing on spectators in the crowd, Rasch said the police received no reports of injuries from where spectators were located on Juniper Hill, near where the carnival was set up.

“The fire was not threatening to anyone in the area,” Rasch said.

He said it was a windy night and that may have carried some sparks into the crowd.
